A loop heat pipe includes an evaporator and a tube hermetically connecting with the evaporator. The evaporator includes a metallic container and a wick structure disposed in an inner surface of the container. The wick structure includes a first wick portion thermally contacting the whole inner surface of the container and a second wick portion enclosed by the first wick structure and contacting with the first wick portion. A number of channels are defined between the first and second wick portions for receiving vaporized working medium. The tube communicates with the channels of the evaporator so that the vaporized working medium can flow from the channels into the tube.
